no equipment-identity-register { isdn E.164_num | point codept_code }] [ include-imsi | map-include-imsi ]
no
Deletes the EIR configuration.
isdn
number
Enter the E.164 number of the EIR.
number: must be a string of 1 to 15 digits.
point code
pt_code
Enter SS7 point code address of the EIR in dotted-decimal format according to variant settings:
-
ITU Range 0.0.1 to 7.255.7
-
ANSI Range 0.0.1 to 255.255.255
-
TTC Range 0.0.1 to 15.31.255
-
or a string of 1 to 11 characters
source-ssn
ssn
Identifies the subsystem number (SSN) to be used.
ssn must be an integer from 1 to 255.
check-imei-every-n-events times
Configures the frequency with which a 'check IMEI' message is sent to the EIR. When set, the SGSN skips sending the 'check
IMEI' message for the first N-1 where IMDI/IMEISV is received.
times :
-
For releases 8.0 and 8.1, the value must be an integer from 1 to 15.
-
For releases 15.0 and higher, the value must be an integer from 1 to 15.
Important |
This feature requires the enabling of verify-equipment-identity for IMEI or IMEISV as specified with the the gmm retrieve-equipment-identity imei command of the call-control-profile configuration mode.
|
check-imei-sub-every-n-events times
check-imei-sub-every-n-events times: Performs IMEI check every N events for each subscriber . times must be an integer ranging
from 1 to 15.
include-imsi
Enables inclusion of IMSI checking during the IMEI check procedure. By
default this function is not included.
map-include-imsi
Enables the inclusion of IMSI parameter in the CHECK_IMEI Request. By
default, IMSI is not included in the CHECK_IMEI Request.
Usage Guidelines
Configure the identity of the EIR that the SGSN uses and the
interaction parameters.
Increasing the
check-imei-every-n-events
frequency enables the EIR to avoid overload as the
number of data-only devices attaching to the network increases.
Example
Configure EIR with point code 1.255.1 to perform IMEI check after
every 61st received Attach Request message:
equipment-identity-register point code 1.255.1 check-imei-every-n-events 62
Configure IMSI to be included in the MAP-CHECK-IMEI operation:
equipment-identity-register point code 1.255.1 check-imei-every-n-events 62 include-imsi
